Title: Improvements in and relating to heat insulation
IPC: F16L59/02
Filed: 1924-01-29
Abstract: 234,535. Bohlander, H. Jan. 29, 1924. Non-conducting coverings.-In heat-insulating coverings for pipes or other surfaces of the kind comprising two or more layers, one of which is characterized by a higher insulation value and the other by a greater mechanical strength, the. insulation is built up on the article to be protected, such as a pipe f, and the outer layer b is of strong self-supporting insulating material having inward extensions e which rest on the article to be protected so that the. loose inner layer a is not loaded or compressed. In applying the insulation the supports e are formed first, then the loose material a is placed in position in wirenetting containers coated with plaster, and finally the outer layer b is applied, the wire-netting protecting the loose inner layer from pressure while the outer layer is setting. For the inner layer suitable materials are Kieselguhr used either alone or in combination with slag-wool, glass wool, cork, or saw-dust, or chalk or magnesia mixed with slag-wool or glass wool, and for the outer layer furnace dust with a binding material such as clay.

Abstract: 1381621 Extrusion casting of sequentially fed cones IKEGAI TEKKO KK and DAI NIPPON INK KAGAKU 18 Jan 1972 [18 Jan 1971] 2428/72 Heading B5A A plurality of cores 2, e.g. pencil leads, or lengths of metal wire, or of pipe, are sequentially fed through an extrusion cross-head die in axially aligned relationship at the same speed that the cores, after being covered with thermoplastics material by the head, are continuously drawn from the head at the same speed as a cutting device is moved in the extrusion direction to sever the extruded plastics transversly at a location intermediate successive cores. The cores 2 are sequentially gravitationally delivered from a hopper 3 into a channel along which they are fed by a reciprocating plunger 5 to the head 6, and from which head they are drawn with the extruded plastics covering, through a sizing plate 11 and a water cooling tank 9, by continuously operating take-off roller pairs 10a, 10a<SP>1</SP>, and 10b, 10b<SP>1</SP>, of which the upper rollers are spring loaded and the lower rollers are driven. The plunger 5 is connected for reciprocation to one end of rigidly connected rods 19, 15, to the other end of which is adjustably connected, at nuts 18, a wheeled carriage 21 carrying a blade or saw cutter 23, which is intermittently or continuously rotated by a motor 24, and reciprocated transversely of the extrusion direction, by an hydraulic cylinder C3, to perform the severing operation as the plastics covering is clamped by a chuck 25 operated by an hydraulic cylinder C2. The plunger 5 and carriage 21 are driven in the extrusion direction by intermittent engagement of a rack 30 on the rod 15, by spaced apart toothed arcs of a wheel 14 which is continuously rotated by a motor 28 and from which a drive is also taken to the lower take-off rollers. Upon disengagement of the wheel 14 from the rack 30, the plunger 5 and carriage 21 are returned by an hydraulic cylinder C1 engaging the rod 15. The cylinders C2 and C3 are controlled to effect clamping and cutting from a limit switch LS1, when actuated by a dog 18 on the rod 15, and the cylinders C1 and C2 are controlled to effect return the plunger 5 and carriage 21 and release of clamping, from a similarly actuated limit switch LS2 when the wheel 14 is disengaged from the rack 30. The cutter 23 is returned to its inoperative position prior to actuation of LS2, upon actuation of cylinder C3 by a limit switch LS3.

Patent GB-627623-A (GB)
Title: Improvements in or relating to electronic circuits
IPC: H03K7/00
Filed: 1947-01-27
Abstract: 627,623. Frequency measuring. HASS, Z. K., and COOP, E. Jan. 27, 1947, No.2466. [Class 37] [Also in Group XL (c)] In a circuit for producing pulses of constant width, at a repetition frequency which is rationally related to that of a controlling wave, a short pulse having the desired frequency relation to the controlling wave is derived from the wave in a device 1, and simultaneously applied to a delay line or equivalent mechanical device 6, having its remote end " shorted," and to a flip-flop 3. The pulse triggers the flip-flop into its unstable state in which it remains until an inverted reflection of the original pulse triggers it back into its stable state. Fig. 3 shows a cathode coupled pair of valves forming the flip-flop, the output of which is taken off through a slicing valve V3. As the mean anode current of V3 will be proportional to the pulse repetition frequency and hence the controlling wave frequency, a meter M in the anode circuit gives a measure of the latter frequency.

Title: Improvements relating to electrical relay arrangements
IPC: H02H3/027
Filed: 1941-02-25
Abstract: 546,546. Electromagnetic relays ; variable resistances. SWITCHGEAR & COWANS, Ltd., and MAXWELL, A. V. Feb. 25, 1941, No. 2573. [Class 38 (v)] [Also in Group XXXVI] In a time-delay relay arrangement for use with overload, directional or earth leakage protection, the relay e which is in circuit with a neon lamp c or like device operates only after a condenser d has been charged or discharged through a variable resistance h, the particular value of which is determined by the strength of the operating current j. In the arrangement shown flow of current j attracts a core i and immerses a plunger h of resistance material a variable amount in mercury g, thereby completing a circuit between DC terminals a, b which charges the condenser d. After the given time limit, the voltage of the condenser is sufficient for current to flow through the neon lamp c and operate the relay e.

Title: A new or improved process and apparatus for the preparation of textiles fibres for spinning
IPC: D01G15/46
Filed: 1930-01-25
Abstract: 339,848. Laurency, G. C. Jan. 31, 1929, [Convention date]. Drawing - frames; carding - engines; sliver-rubbing apparatus.-A fleece or layer of fibres is converted into rovings ready for spinning by piercing it with very fine conical points reciprocated vertically between the rollers which draw the fibres, the fibres being displaced to right and left by the widening of the separation lines to form independent groups between the lines, each group being subsequently condensed in known manner and constituting a roving ready for spinning into yarn. An endless apron F, passing around a tension roller I and a roller B formed with spaced rounded flutings, draws fibres from a doffer A at a point m where a resilient segment G is pressed against the roller, each fluting forming a resistance line which holds the fibres firmly while the free space between the flutings allows the apron to yield and lessen the tension. The segment G comprises a single piece of slightly smaller diameter than the roller B with its apron F and is held in place by springs J fixed upon a rigid bar K adjustably suspended from the ends of the shaft of the roller B. A roller C,. provided with needles or carding teeth, cooperates with a second segment G' to draw the fibre from between the apron F and roller B and to feed it to an apron-covered fluted roller D identical with the roller B. Between the rollers C and D, a rake M with sharp conical teeth reciprocates vertically several times during the passage of a fibre and its teeth penetrate between the fibres to group them into slivers and arrange them in parallel relationship. Hooks O on the teeth catch stray fibres and bring them into the groups. Beyond the roller D a second rake N is arranged. When treating short fibres, this rake is stationary or moves vertically, both rakes in the latter case being mounted on a rocking lever P having unequal arms adapted to draw the rake M clear of the fibre but maintain the rake N in contact with it. If the fibres treated are very long, the rabe N is arranged to move laterally. Finally, a plain roller E co-operating with a segment G<111 >is provided with an apron F<111> which constitutes the upper member of a pair of known rota-rubbers which condense the grouped fibres into rovings. With long fibres, the fibres may be taken from the roller C by rollers a, Fig. 5, pressing on an ordinary fluted roller B<1>, an oscillating rake M<1> grouping the fibres as above described.
